(GI50 = 1.66 μM) appeared to be the most active agent of this series. Furthermore, 3c attenuated topoisomerase I-mediated DNA relaxation at low micromolar concentrations. These results indicated that fluorenones have potential to be further developed into anticancer drugs.
设计,合成和筛选了一系列的2,7-二叠氮芴酮,并通过SRB分析进行了筛选。一些合成的化合物在亚微摩尔范围内表现出抗肿瘤活性。通过NCI筛选系统还选择了10种化合物(3a,3b,3c,3g,3j,3l,4a,4h,4i和4j),而3c(GI 50 = 1.66μM)似乎是该系列中活性最高的试剂。此外,3c低微摩尔浓度时,可减弱拓扑异构酶I介导的DNA松弛。这些结果表明,芴酮有潜力进一步发展成为抗癌药物。
